Patented. Aug. 19, 1930 GERTRUDE VAN BREE, OF CHICAGO, ILLINOIS GUARD non GAS BURNER Application filed May 9,

This invention relates to certain novel im provements in protective devices and particularly to protective devices for gas burners and the like.

The salient object of my inventionis to provide a protective device which may be associated with gas burners that will function to prevent extinguishment of such burners at undesired times. The device is arranged in a manner such thatexcessive air currents and boiled over water will be prevented from engaging a portion of the flame from the burner so that the entire flame will not be extinguished. 7 Another object of the invention is to pro vide a device of the above named character which may be expeditiously mounted in position.

A further object of the invention is to provide a device of the above named type which will be simple and economical in operation.

Other and further objects will be apparent from the following description wherein reference is made to the accompanying drawing wherein:

Fig. 1 is top plan view of a burner to which my improved device has been attached,

Fig. 2 is a sectional view taken on the line 22 on Fig. 1, and

Fig. 3 is a sectional view taken on the line 3-3 on Fig. 1.

A preferred form of construction for my invention is shown in the accompanying drawing as being attached to a burner 10, of approved form, which has arms 11 extend ing. from the central portion-12 thereof. In

the upper surface of the arms 11 and portion 12 a plurality of holes 13 are provided thru which the ignit-able fluid passes for ignition thereabove. My improved device is intended to be mounted on one of the arms 11 but if the burner is not provided with such arms, my device is intended to be mounted in a position such that it covers a portion of the openings 139 I 1929. Serial No. 361,821.

My improved device as generically indicated by 14 is preferably formed from a blank of relatively flat bendable material. The blank includes a lower portion 15 of relatively narrow width that is intended to be dis-, posed below one of the arms 11 so that a portion thereof will extend along the sides of said arm. This lower section 15 is preferably formed to be substantially U-shaped. The upper portion 16 is wider than the por-' tion 15 and is disposed above and spaced from the upper surface of the arm 11. The portion above the outer end of the arm 11 is bent downwardly to provide a flange 17. The section of the portion 17 opposite the flange 17;; is offset downwardly as indicated at 18. In this manner a chamber 19 is defined in the portion 16. The section 15 embodies suflicient innate resiliency to prevent displacement of the device 14.

In use, the fuel emitted from the openings 13 is ignited and therefore a flame is enclosed by the section 16 in the chamber 19. By reason of the sides of the section 16 and the 01fsetportion 18 and the flange 17 excessive air;

currents, water or the like from a vessel being heated above the burner 10 will be prevented from entering said chamber 19. Therefore, if the flame above the other of the openings 13 is extinguished the flame in the chamber 19 will continue and this will serve to reignite the extinguished flame when the cause of the extinguishment is removed.

In the foregoing description I have set forth a preferred form of construction for my;

invention but it is to be understood that this V is capable of variation and modification in size, shape, and material without departing from the spirit and scope of the appended claim.

What I claim is A guard for gas burners formed from single blank of bendable material and including a tubular body comprising a relatively narrow U-shaped lower portion, an upper.

portion longer than the lower portion and integral with the walls of the U-shaped part, said upper portion having its ends extending beyond the ends of the lower portion and having one end bent downwardly to form an overhanging flange, an inwardly and downwardly offset portion at the other end of the upper portion whereby to provide an elongated chamber in the upper portion of the tubular body.

In witness whereof, I have hereunto set my hand this 21st day of March A. D. 1929.
